It is a further object of the present inventionto provide a device which can be .en'ameled or plated on the side adjacentthe'door' opening and which cooperates with the door or portions carried thereby in such a manner that danger of cracking or'chipping the enamel is eliminated. V v r A still further object is to provide a combined pivotalsupport and door-stop which is economical of manufacture, facile of application to the oven frame, and which is sightly in appearance. I Still further objects will-readily occur to those skilled in the art upon reference to the following description and the accompanying drawings in which h Fig. l is a partial side view of an oven and door therefor, the device of'the present invention being shownin dotted lines.

Fig. 2 is aside view of the pivot on the left handsideof the frame, the door being shown in its open position, and partially in section, the viewbeirig'taken from the inside of the oven. 1 V V Fig. 3 is a sideview of the left'hand pivot taken from the outside ofthe oven, the outer portion ofthe frame being broken away and taken from inside the'oven, the door being A v N a r onthe stopflugQZj to which shown as closed.
